Developing an integrative urban resilience capacity index for plan making

Urban resilience assessment can help planners understand the status of resilience in an urban system and identify needs for improving resilience capacities. The issues related to urban resilience are complex because of multiple urban system components, threats from different sources, and uncertainty of the future. Urban resilience theories have progressed to consider an urban system as an integrated complex system; however, urban resilience assessments are inconsistent and underdeveloped in assessing an integrated urban system for different threats at various uncertainties. In an effort to address this deficiency, we propose to develop an Integrative Urban Resilience Capacity Index (IURCI) for assessing urban resilience capacity for all threats. To improve the quality of urban resilience assessment, the IURCI considers urban physical form, spatial structure, preparation for future, and performance after plan implementation to measure resilience capacities of absorption, mitigation, and adaptation. It is built in a Scenario-Based Planning Support System (SB-PSS). The SB-PSS is a framework and an open system that integrates IURCI with scenario generation, modeling, and assessment to inform the public, planners, and other stakeholders about the consequences of different planning policies and to assist them make decisions for implementing a preferred scenario.
